From: oldbucsfan at hotmail dot com Operating system: Windows Server 2012 R2 PHP version: 7.0.14 Package: Apache2 related Bug Type: Bug Bug description:Wordpress crash with PHP7 Implode() Description: ------------ Continuously hitting my Wordpress 4.7 website using abs.exe (or just random access) causes Apache 2.4.23 to crash with the following message: AH00428: Parent: child process 15452 exited with status 4294967295 -- Restarting. I have disabled all but php_mysqli and I still get the error. Tried disabling all Apache modules that I could, same problem. This problem was likely present in earlier versions of Wordpress. This error does not occur with PHP 5.6.29. Backtrace suggests the problem may be related to implode(). Actual result: -------------- I have run a backtrace and got this: *********************** * EXCEPTION DETAILS * *********************** DetailID = 1 Count: 1 Exception #: 0X80000003 Stack:
